Q.Lattice enthalpy for $NaCl$ is $788 \text{ kJ/mol}$ . This means:

788 \text{ kJ}

is released when

1 \text{ mol}

NaCl(s)

is formed from gaseous ions

788 \text{ kJ}

is absorbed to separate

1 \text{ mol}

NaCl(s)

into gaseous ions

Both A and B

None of the above

The correct solution involves applying the fundamental concept to derive the final value step by step...
